Abstract
The invention relates to a POY (polyester pre-oriented yarn) spinning method and device by using a FDY (fully drawn yarn) spinning device. The POY spinning method is realized by using the FDY spinning device, wherein the FDY spinning device comprises a box body, a cross air blasting window, a chimney, a first hot roll, a second godet and a winding head. When the POY spinning is preceded, an oil tanker of the original FDY spinning device is stopped using, an oil nozzle is additionally arranged above the chimney for feeding oil, and a guide wire hook and combtype wire-dividing device of the first hot roll are provided with extension rods for moving outwards in a pre-network so as to move the spinning central line outwards; meanwhile, a second hot roll of the original FDY spinning device is stopped using, the first hot roll and the second godet are reserved, the filament bundling passes through the first hot roll for one time and winds 4-5 circles on the second godet for further moving the spinning central line outwards, and then enters into a wiring head for realizing winding. The method provided by the invention can produce high-quality POY on hot-roll type FDY equipment with the advantages of less transformation investment, simple method and fast transformation speed, thus realizing flexible production between the FDY and POY products at any time.
Description
Technical field
The method and apparatus of POY is produced in the repacking that the present invention relates to a kind of FDY device.
Background technology
For adapting to market changeable, domestic existing many producers achieve the technological transformation of producing POY product on FDY production line, and obtain good effect.Generally there are three kinds of methods: first method utilizes former FDY device, directly produces POY; Second method removes FDY hot-rolling, increases draw-off godet; The third method utilizes FDY hot-rolling, but by overhanging for the first hot-rolling concordant with the second hot-rolling etc.
Above-mentioned three kinds of FDY devices produce the technological transformation of POY product, and first method production stability is poor, is generally difficult to successfully, and the second, the third method retrofit work amount and input are comparatively large, are unfavorable for the FDY that resumes production.
Chinese invention patent application (application number: 03112239.6 applying date: 2003-05-30) discloses a kind of processing method of carrying out islands-in-sea type fibre POY production based on islands-in-sea type fibre FDY production equipment, cut into slices as raw material with general fibre grade polyester chip and water-soluble polyester, respective drying machine is dry, the melt extruded of screw extruder becomes can the polyester fondant of spinning, and the spinning pump accurate measurement of conventional polyester melt after filtering, is delivered to by melt distributing pipe, the composite component be incubated by spinning manifold is accordingly evenly distributed to by each isometric melt ltanifold; The two kinds of polyester fondants mixed in composite component spray from assembly, oil pass through spinning shaft through cross air blowing device cooling forming, oil nozzle, and pre-the nozzle of interlace blows net and is drawn to the first hot-rolling, the second hot-rolling, tow is rolled into islands-in-sea type fibre POY spinning cake by being wound head after the second hot-rolling.
But above-mentioned FDY device fabrication POY exists the first godet system and the second godet system not on same vertical plane, FDY spinning centre-to-centre spacing and winding center be not apart from the first-class problem of same vertical plane.
Summary of the invention
In order to solve above-mentioned technical problem, an object of the present invention is to provide a kind of method of being carried out POY spinning by FDY device for spinning, the POY that the method is produced on FDY device, transformation less investment, can normally run for a long time after transformation, product quality reaches the Product Level of POY production line, and is easy to flexibility conversion between FDY to POY, POY to FDY.Another one object of the present invention is to provide the POY device for spinning transformed by FDY device for spinning.
In order to realize first above-mentioned object, present invention employs following technical scheme:
A kind of method of being carried out POY spinning by FDY device for spinning, described FDY device for spinning comprises casing, quenching air window, path, the first hot-rolling, the second godet roller and winding head, when carrying out POY spinning, the oil tanker of former FDY device for spinning is stopped using, above path, set up oil nozzle oil, and traveller and combed sub-wire device under network pre-before the first hot-rolling are moved by arranging outside extension bar, make to move outside spinning center line; Meanwhile, the second hot-rolling of former FDY device for spinning is stopped using, and retains the first hot-rolling and the second godet roller, and tow once by the first hot-rolling, and moves spinning center line at the second godet roller outside 4 ~ 5 circles are further, and then tow enters described winding head and realize winding.
In order to realize second above-mentioned object, present invention employs following technical scheme:
The POY device for spinning transformed by FDY device for spinning, described FDY device for spinning comprises casing, quenching air window, path, the first hot-rolling, the second godet roller and winding head, this POY device for spinning is stopped using the oil tanker of former FDY device for spinning, above path, set up oil nozzle oil, and traveller and combed sub-wire device under network pre-before the first hot-rolling are moved by arranging outside extension bar, make to move outside spinning center line; Meanwhile, the second hot-rolling of former FDY device for spinning is stopped using, and retains the first hot-rolling and the second godet roller, and tow once by the first hot-rolling, and moves spinning center line at the second godet roller outside 4 ~ 5 circles are further, and then tow enters described winding head and realize winding.
The present invention efficiently solves hot roller FDY device fabrication POY and there is the first godet system and the second godet system not on same vertical plane, FDY spinning centre-to-centre spacing and winding center distance be not in the first-class problem of same vertical plane, achieve and produce high-quality POY on hot roller FDY equipment, transformation less investment, method is simple, transformation speed is fast, realizes flexible production between FDY, POY product at any time.In actual production, the range of product size of producing can control at (75 ~ 200) dtex/ (36 ~ 48) F.
